Development of NC5340TGJ Cementing Truck with Double Motors and Double Pumps

In view of the development requirements of oil and gas fields in mountainous, desert and hilly areas, in order to solve the problems of high pressure, continuous cementing and mud density control accuracy, the development of NC5340TGJ double machine and double pump cementing cement truck was carried out, and the key technologies such as electronic control system integration, automatic mixing algorithm and driving stability check were developed. The model cementing truck adopts two sets of driving and pumping devices. The two sets of devices can realize simultaneous or separate operation. The maximum output pressure is 100 MPa and the maximum displacement is 3 m³/min.Moreover. it has three slurry mixing modes: manual, automatic and semi-automatic. The whole vehicle has reasonable layout, compact structure, and its operation stability and reliability meet the requirements of current oil and gas field cementing operation. The cementing truck has completed surface casing cementing, technical casing cementing and other well construction operations. The application results show that NC5340TGJ cementing truck has completed surface casing cementing, technical casing cementing and other well construction operations, and the density of cement slurry fluctuates within ±0.02 g/cm³.
